Additional Product Information


Main fabric

  • 96% Polyamide
  • 4% Spandex

What is the fit 580 i-soft base layer ski top?

The 580 I-Soft, Base Layer Ski Top is designed to be slim fitting. It acts as a tight-fitting 2nd skin which reduces friction.

What are the benefits of polyamide?

Polyamide has the highest strength of all textile raw materials (even when wet) and is very stretchy. It is breathable and offers excellent humidity management, while reducing odors through its natural properties, as well as good thermoregulation. These specially textured super-soft yarns give fabrics a silky, natural feel. Ideal for tight, seamless clothing.

Technical structure of the product

With its smart body mapping technology and brushed polyamide fiber resulting from the I-SOFT technology, this 2nd skin gives kids a feeling of warmth that is evenly distributed throughout their body.

How should kids dress to ensure they keep warm on the ski slopes?

To make sure you stay warm and dry, we recommend using the 3-technical-layer rule: Layer 1 or a 2nd skin, to stay dry. Layer 2 or an insulating layer, to keep the heat in. Layer 3 or a protective layer, to protect against bad weather.

A product-specific environmental rating

The product's environmental footprint is calculated for its entire life using various indicators. An overall score from A to E is given to help you easily identify the most eco-friendly products by comparing products of the same type (T-shirts, pants, backpacks, etc.)



Product testing

All Wedze products are created, designed, and developed in the Mont Blanc Valley. They are then tested under the same conditions as you would experience in real-life use (snow, cold, powder snow, etc.). The design teams ensure that the program for which the product has been designed and developed matches perfectly with its use in the field.
